Pillow case

ABSTRACT

This disclosure discloses a type of pillowcase, comprising an upper pillow sheet and a lower pillow sheet, which are both made of Spandex knitted fabric, and the lower pillow sheet is designed with an opening in the middle. The pillowcase in this disclosure is made of Spandex knitted fabric, and it has high elasticity, low elasticity loss and high recovery rate. It is easier to place the pillow inner into the pillowcase through the opening set on the lower pillow sheet. At the same time, it can prevent the pillowcase from being torn apart from the opening by excessive force, facilitate the replacement of pillow inner, and save time and manpower. It is particularly suitable for hotels, beauty parlors and other places where pillow inners need to be replaced frequently.

TECHNICAL FIELD

The disclosure belongs to the technical field of bedding, in particularto a high elastic pillowcase.

BACKGROUND

The existing pillowcase usually fills the pillow inner in the followingways: 1. On the back of the pillowcase, two lower pillow sheets arearranged to form an opening for filling the pillow inner, which must bestuffed into the pillow case at a very deep distance, leaving theopening easy to be torn by a little excessive force. 2. Sewing the threesides of the upper and lower pillow pieces of the pillowcase together toform a hollow space, and filling the pillow inner from the open end. Ifthe long side of the pillowcase is left open, then the pillow innerwould slide out of the pillowcase easily; If the short side of thepillowcase is left open, the pillow inner would be stuffed into thepillowcase at a very deep distance. 3. A zipper is installed on thepillowcase. This is cumbersome to operate and the zipper is easy to bedamaged.

SUMMARY

The purpose of the present disclosure is to overcome the shortcomings ofthe existing technology, and to provide a pillowcase that is easy to befilled by the pillow inner. The invented pillowcase is easier for thepillow inner to be placed into the pillowcase through an openingarranged in the middle of the lower pillow sheet. At the same time, itcan prevent the pillowcase from being torn apart from the opening byexcessive force, so as to conveniently replace the pillow inner, savetime and manpower.

The purpose of the present disclosure is achieved as follows:

The disclosure relates to a pillowcase, which comprises an upper pillowsheet and a lower pillow sheet, both are made of knitted fabric, and anopening is arranged in the middle of the lower pillow sheet.

The shape of the above-mentioned opening is, circular or square.

Optimally, the above-mentioned knitted fabric is Spandex knitted fabric.

Optimally, the edge of the above-mentioned opening is stitched with edgewrapping.

Optimally, the width of the above-mentioned edge wrapping is 0.5-3 cm.

Optimally, the elasticity of the knitted fabric is 5%-200%. In thistechnical solution, the elasticity is the ductility of the fabric. Theabove-mentioned fabric can be increased to 105%-300% when beingstretched.

Compared with the existing technology, the present disclosure has thefollowing advantages:

The pillowcase of this disclosure uses Spandex knitted fabric, which hasthe characteristics of high elongation (500%-700%), low elasticitymodulus (200% elongation, 0.04-0.1 g/d) and high elastic recovery (200%elongation, 95%-99%). Therefore, Spandex knitted fabric can be easilystretched. It can be seen that the pillowcase made of Spandex knittedfabric has high elasticity, low elasticity loss and high recovery rate.It is easier to place the pillow inner into the pillowcase through theopening set on the lower pillow sheet. At the same time, it can preventthe pillowcase from being torn apart from the opening by excessiveforce, facilitate the replacement of pillow inner, and save time andmanpower. It is particularly suitable for hotels, beauty parlors andother places where pillow inners need to be replaced frequently.

In this disclosure, the lower pillow sheet is made of Spandex knittedfabrics. Even if there is no edge wrapping to the rim of the opening,there will be no unraveling or fraying. Therefore, in the manufacturingprocess, the lower pillow sheet only needs to be perforated without edgewrapping, and there will be no unraveling in use.

The pillowcase opening of this disclosure is arranged on the lowerpillow sheet, and contacts the bed face downward after filled with thepillow inner, which neither affects the normal use of the pillow norcauses the pillow core to become dirty easily because of the opening.

In this disclosure, the edge of the opening of the lower pillow sheet issewn wrapped to make the pillow case more elegant in appearance.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Now comes the comprehensive and clear description of the embodiments ofthe disclosure given with reference to the accompanying drawings. It isobvious that this disclosure is not limited to the present embodiment.

Embodiment 1

This embodiment provides a high elasticity pillowcase, as shown in FIG.1, including the upper pillow sheet and the lower pillow sheet 1, whichare both made of Spandex knitted fabric with 5% elasticity. The lowerpillow sheet is provided with an elliptical opening 2 in the middle. Thepillow inner can pass through the stretched elliptical opening 2.

Embodiment 2

This embodiment provides a high elasticity pillowcase, as shown in FIG.1, including the upper pillow sheet and the lower pillow sheet 1, whichare both made of Spandex knitted fabric with 100% elasticity. The lowerpillow sheet is provided with a circular opening 3 in the middle. Theedge of the circular opening is stitched with 0.5 cm edge wrapping 5.

Embodiment 3

This embodiment provides a high elasticity pillowcase, as shown in FIG.3, including the upper pillow sheet and the lower pillow sheet 1. Thelower pillow sheet 1 is made of Spandex knitted fabric with 200%elasticity. The lower pillow sheet is provided with a square opening 4in the middle.

Embodiment 4

The difference between this embodiment and embodiment 3 is that thelower pillow sheet in this embodiment is 150% elasticity Spandex knittedfabric.

The above embodiments are only examples and not the only embodiment ofthe present disclosure, and any non-creative changes to the presentdisclosure are considered to be within the scope of protection of thepresent disclosure.
